deposits within the cylinders. A- further object is to provide a device which is automatically operated.

For further comprehension of the invention, and of the objects and advantages therezlevice as it would appear when attached to of, reference will be had to the following description and accompanying drawing, and to the appended claim in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing shows my improved an engine.

Fig. 2 is an enlarged central longitudinal sectional view of the automatic needle valve used in combination with my device.

Fig. 4 is an enlarged central longitudinal sectional view of the Venturi tube used in connection with my improved device. 7

Referring to the accompanying drawing, it will be seen that the hydrocarbon engine 10 of ordinary construction and design is provided with an exhaustmanifold 11, and an intake manifold 12 which communicates with the carburetor 13 and'the fuel intake member 14.

From the foregoing description it will be seen that the common engine is used in combination with my improved device. I

Myimproved device consists in general of. a container 15 attached to any convenient place on the engine 10, such as designated by the numeral 16 on the accompanying drawing. The lower extremity of the tube 17 is connected with the casing '20 from which the tube 17 is connected to the inlet an automatic valve casing20 in which the.

valve 21 is slidably mounted. The valve 21 is provided with a stem 22, an enlarged head 23 with its periphery being a slidable fit in the casing 20, and a guide 24 having an the'seat 26 formed in the casing20.

The tube 17 is also provided with aperture to accommodate slidably the valve stem 22, and a 'spring'25 superimposed between the enlarged head 28 and the'guide 24. The foregoing construction being such as will normally hold-the valve 21 against The Venturi' tube 271is a slidable tube17, and is held in place by means of a set screw 28, or any similar suitable threaded member. The adjustable air inlet comprises an elongated slot 29 conveniently located in thetube 17, and a tubular member 30, a

slidable fit on the tube 17 and having an elongated slot 31 and a set screw located therein threadedly attached to the tube 17, as a means of securing any desired opening of the said elongated slot 29.

It will be understood that the relative positions of the .various members comprising my improved device is clearly shown in Figure 1 of the accompanying drawing,'and that said various members are suitably connected to the said tube, which is cut and threaded as may be required. A Referring to the operation of my improved so I device, the container 15 is'filled with Castor 1 oil and the shut off valve is opened. When theengine is running, by means of the suction in the intake manifold 12 andin the tube 17 the valve stem 22 will be sucked or drawn from its seat 26, allowing a certain amount of the *castor oil in the container 15 to be sucked into the intake manifold 12 where it will be mixed with the vapor from the carburetor 13, and then sucked through the intake valves, not shown on the accompany; a

and then into the ,cylindersof tioned element is of ordinary design, and V that same may be replaced by various differ- 'ent sizes of Venturi tube asmay be desirable I to engines of different characteristics.

It will be further understood that my improved device may be made of anysuitable materials such as commonly used in devices 1 of this nature. r v, 7

While I have above described the pre: ferred form, construction a-ndiarrangement of the several elements employed, it will be.

understood that the device is nevertheless,

I sus eeptibl 6f considerable modification therein, and I therefore reserve the privilege "of resorting to all'such changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

7 Having thus described my inventiomvvhat 'Iclaim as new, and desire to protect byLetters Patent of the' United States is as Mechanism for supplying oil to an internal combustion engine comprising an 011 reservvoir,a'tul'oe'for conveying oil from said resplacement thereof, the" tube for conveying oil fromthe reservoir to the manifold bein provided with an air inlet, a tubular memtube and means for adjustably fastening the tubular member for regulating the mixture of air Wit-hthe oil'from said reservoir, and an automatic valve disposed in said latter men tioned tube for controlling the flow of oil 'ber' slid'ably mounted on the last mentioned I from said reservoir, said valve being. adapted to be opened by the suction of said engine. In testimony whereof I have afiixed my signature. I V
